Abstract

A load center includes an enclosure, a first power input, a second power input, a first circuit breaker having a line terminal electrically connected to the first power input and a load terminal, a first bus electrically connected to the load terminal, a number of independent second circuit breakers powered from the first bus, a second bus, a number of independent third circuit breakers powered from the second bus, and a transfer switch having a first input electrically connected to the first bus, a second input electrically connected to the second power input, and an output electrically connected to the second bus. The transfer switch selectively electrically connects one of its first and second inputs to its output. The first bus and the second circuit breakers power only a number of non-critical loads. The second bus and the third circuit breakers power only a number of critical loads.
